There seems to be a persistent and major bug in the Montage in that track effects can fail to render. The plugin in question is Focusrite Red 3 Compressor. This plugin is not set to be bypassed, and Montage Effects in the track inspector are turned on (green). No matter what settings I try, the Montage plays back correctly with the compressor settings but the rendered file is at the original volume, as if no compressor had been used.
Note that the Master Section is set to 0 dB and that loudness is handled directly inside the Montage. Updating to WaveLab 10.0.40 did not help. I’m using macOS 10.15.5.
The following screenshots show all the Montage and render settings.
Thanks in advance for any help. As far as I can tell this appears to be a bug.
